Kube12b / Kube10b / Kube8b Subwoofers
Explore new dimensions in sound with Kube, KEF’s powerful range of subwoofers that open up sound’s
hidden depths.
Each elegantly designed, fully sealed unit unleashes explosive power eortlessly, intuitively, intelligently. iBX
technology extends the bass depth dynamically, unlocking the full potential of the driver’s power at normal
listening levels or even the most extreme. And with KEF’s unique capability to design, build and integrate
the driver in-house, we take optimisation to a whole new level. Delivering immersive music and home
theatre sounds that drive you deeper into the heart of the performance.
Immersiveness
Go deep or go home. KEF’s design and engineering team worked in chorus to develop iBX. This Intelligent
Bass Extension algorithm creates an extended depth that unlocks the full potential of the custom driver.
Giving you unparalleled precision and ultimate synchronicity between amplier, driver and sealed cabinet.
Easy conguration
Your room, your rules. Kube subwoofers oer unmatched exibility in conguration. With a range of LFE,
line & speaker-level inputs, Phase selection and 3 DSP controlled EQ settings to help match your sub to
any room placement, you’re in control right out of the box. Set up the Kube where it’s most convenient
to you, match it to any main speaker or with any type of music system and start exploring new depths in
your sound.
Integration
We’re on the same page. KEF is quite possibly the only high-end manufacturer who designs, engineers
and assembles the driver, cabinet and circuitry in-house. This level of integration is the hallmark of our
commitment to pure sound and the Kube stays true to that ideal. What you get is a driver and amplier
so perfectly attuned they sing in absolute harmony.
